Business Case & ROI
A business case generator that gives your champion a page to forward

Short answer
Key takeaways
- Every proposal includes a one-page business case your buyer builds for their approver, with no login and no spreadsheet.
- The buyer sets the numbers, so your champion can explain every figure with confidence.
- Approvers see return over the term, months to payback and the net after each of the first three years at a glance.
- You see when the business case is read and for how long, often the moment a deal starts being decided.
The person you demo to is rarely the person who signs. Your champion has to walk into their boss's office and explain what the problem costs, what you cost and when it pays back. Most champions write that page themselves, late at night, from memory. AfterDemo puts a business case generator inside every proposal, so your champion arrives at that meeting with a clear, confident one-pager instead of a blank page. If you'd rather write one by hand, our business case template walks through every section.
A page your champion is proud to forward
Inside the proposal you sent, the buyer builds a one-page business case:
- The problems, each with a monthly cost. The buyer picks the ones that count and can add their own.
- What it costs today, per month and per year.
- Your price and term.
- The numbers an approver reads first: return over the term, how many months until it pays for itself, and the net after each of the first three years.
It takes minutes. No spreadsheet, no login, no waiting on you. The result is a clean page they can forward or print and put on their approver's desk.
Why the buyer builds it, not you
Every approver discounts a vendor's ROI slide. They know who made it. A case built from the buyer's own estimates lands differently: the champion can explain every number because they chose it.
That's what turns a champion into a seller. They're not repeating your pitch; they're presenting their own case, in their own words, with their own figures. And because it's built from the problems they told you about on the call, it connects directly to everything else in your proposal.
Know when the deal is being decided
Because the business case is a section of the proposal, you see when it's opened and for how long, just like any other section. That's often the moment a deal moves from "interested" to "being decided".
If your champion builds the case and a new colleague appears soon after, you know it's on its way up the chain. That's your cue to offer a short call with the approver, or to send the one answer they're likely to need. Here's more on proposal tracking.
What to say when you send it
You don't need to explain the business case at length. One or two lines in your email are enough. For example:
- "There's a business case section near the end. Put your own numbers in and it works out the payback. It's built to forward to whoever signs off."
- "If it helps with your finance director, the business case page turns the costs you mentioned into a one-pager. Change anything that looks off."
Then watch what happens. When your champion opens it and a new name appears soon after, the case is doing its job. If it hasn't been opened yet, ask your champion how they plan to get sign-off, and offer to help.
Simple on purpose
Small-company approvers usually want to know two things: what does this cost us today, and how fast does it pay for itself? The business case answers both on one page, in plain language, without a finance degree. If you want to explore the numbers further, try the free ROI and payback calculator.

Questions people ask
Who fills in the business case, the seller or the buyer?
The buyer. It sits inside the proposal, and the buyer sets the numbers. A case built from the buyer's own estimates is easier for them to defend in front of their approver.
Does my buyer need an account to build it?
No. Buyers open the proposal with a link and never log in or create an account.
How does the business case help my champion?
It turns the costs they described on the call into a one-page case with the payback worked out, ready to forward or print. Your champion walks into the approval meeting with something their boss can say yes to.
Can I try it without signing up?
Yes. The free Business Case Builder at afterdemo.com/tools/business-case-builder is the same builder. It runs in your browser and saves nothing.
